I am planning to sow my Early Onward peas this weekend, but can't find anything definitive about how high they grow. Most of the seed suppliers say 2ft, but a thread last year had some at 4 feet tall. ???

I've never grown them before so would appreciate some advice on how high to make the supports - probably canes with pea netting / string as I don't have any twiggy sticks on hand. Any other advice would also be welcome.

I use pig wire (the wire fencing used to enclose fields), its about 4ft tall and the onwards peas I grew last year just managed to grow about 6 inches over the top. the height of the peas depends on the condition of the soil ie :- moisture content retention
